Hinged on the size and quantity of your home appliances, a 10000W generator will normally imply that you have to let go some circuits within your home in order to allow the maximum watts that the generator produces. Meaning, you would have to select some specific circuits that should be run by the generator.

Furthermore, while you might not want to overload your generator in order not to develop a circuit breaker trip off; it’s best you calculate the required consumption of power (although difficult), just to meet the capability of your generator. Specifically, there are numerous household appliances that switch on automatically as a result of their thermostat features; hence you can’t completely have total control on the amount of electricity you consume. To estimate the required consumption that might need the capability of a generator, you can begin by looking around your home and listing the essential equipment that will be used regularly. Advisably, you can use cooking gas for preparing your meals when running a generator rather than to use electric stoves which consume massive quantity power.

Durostar DS10000E 10000 Watt Gas Generator

Durostar DS10000E could have been the star of this list if only one thing could be avoided which we will come to later. The Durostar DS10000E is well set in this segment of generators with comparable specifications with the higher end competitors in this comparison and its highly affordable prices. It is run with a 420cc DuroMax OHV engine which is air cooled to offer a longer run time. This engine churns out a nice 16 HP of power and produces 10000 peak watts of power as well as 8000 watts of ratted power. This power generator is more than adequate for all the work that you can throw at it and ensure that RV or home is powered in case of emergencies as well as can help you out on a job site. The caveat of this generator as mentioned before is that it only offers a measly 2 120V 20A 3 prong outlets which are barely enough for anything. Though it also offers 1 120v/240V 30 Amp twist lock outlet, 1 120V 30 Amp twist lock outlet, and 1 120V/240V 50 Amp heavy duty outlet it still might end up being short when required and hence could a be a deal breaker for most. This generator is backed by a 3 year residential warranty and a 1 year commercial warranty which is on par with all other generators in this list of comparison.
